Good story, Not enough for a whole film

A film with more than the usual spoiler issues. Talking about it in any detail feels akin to handing you a gift-wrapped present and saying, "I hope you like it -- It's a thriller about a diabolical secret experiment."

This is a must-see and one of the best documentaries - and films - of this year.

An old-fashioned movie made with new-fashioned finesse.
